^^^^ not for BTC withdrawals.....
craptsy don't have fiat.
Sure, but still...
Then, once or twice I've been transferring alt-coins in the midst of a 51% attack or with low network hash because it's not the most profitable anymore. I can't blame the exchange for lost or unconfirmed coins. In fact, I have some GLD unconfirmed for more than a month now, when it forked or a bug was "fixed" or whatever.
Except if an exchange is scamming/stealing, I have some tolerance for their problems
